Re: Scrollbar misbehaving w/ ROText ?

OK, I've played with a few things in the example I sent, and
here's my results:

1) changed from Scrolled() to explicitly creating the scrollbar
widget - no effect

2) changed from ROText to Text - no effect (ie, the problem
exists in Text as well as ROText)

3) I changed the number of lines loaded into the text widget
Interestingly, up to about 220 lines, everything behaves properly;
after that, the scrollbar seems to lose track of the size/location
of the slider

4) Changing the font size seems to have some effect on the
number of lines that breaks it; bigger fonts seem to break it
at around 150-170 lines.

I suspect there's some subtle interaction between the resizing
of the slider down to/beyond its minimum size, and the way the scrollbar
tracks it location (possibly due to some precision issues with
font metrics ?)

Anyone familiar enough w/ tkWinScrlbr.c to know what to look for ?
